Summary

Exploring the efficacy of PD-1 inhibitor combination therapy strategies for adjuvant therapy in a population that has not achieved major pathological regression after neoadjuvant immunotherapy for non-small cell lung cancer: a multicenter, phase II clinical study

Detailed description

This study explores the potential resistance problem in patients with low response rates after neoadjuvant ICIs treatment by addressing their potential resistance problems through an adjuvant immune combination regimen of ICIs, with the aim of providing a personalized choice of perioperative regimens for patients with early stage II-III resectable NSCLC, and to reduce the risk of postoperative recurrence and death in patients.

Conditions

• Non Small Cell Lung Cancer

Interventions

Type	Name	Description
DRUG	IBI363	IBI363 is the worlds first PD-1/IL-2α bispecific antibody fusion protein with an IL-2 arm that has been designed and modified to retain CD25 (IL-2Rɑ) activity to maximize efficacy and high selectivity, and to reduce binding to IL-2Rβγ to reduce systemic toxicity, whereas the PD-1 binding arm allows for blockade of PD-1 and selective delivery of IL-2. Therefore, IBI363 has the ability to simultaneously block the PD-1/PD-L1 pathway and activate the IL-2 pathway, which can more effectively activate tumor-specific T cells. IL-2, as an important cytokine for activating tumor-specific CD8+ T cells, is mechanistically complementary to immune checkpoint inhibitors, and can reverse T-cell depletion, thereby overcoming immune resistance.
DRUG	LM-108+Sintilimab	LM-108 is a humanized monoclonal antibody targeting the human chemokine CC receptor 8 (CCR8) and is able to modulate the tumor microenvironment by specifically removing tumor-infiltrating regulatory T cells (Treg) through antibody-dependent cell-mediated cytotoxicity (ADCC) without affecting peripheral Treg.
DRUG	IBI310+Sintilimab	The principle of CTLA-4 combined with PD-1 therapy is to fully relieve the inhibition of T cells by blocking both CTLA-4 and PD-1 immune checkpoints simultaneously.CTLA-4 inhibitors mainly work in the initial immune response stage by blocking the binding of CTLA-4 to B7 and enhancing the activation and proliferation of the initial T cells; whereas PD-1 inhibitors restore the anti-tumor activity of activated T cells by blocking the binding of PD-1 to its ligand PD-L1/PD-L2 and restoring their anti-tumor activity. and its ligand PD-L1/PD-L2 binding, lifting the functional inhibition of activated T cells and restoring their anti-tumor activity. Combination therapy can fully activate T-cells, improve the immune system\'s ability to recognize and attack tumors, enhance the anti-tumor immune response, and overcome the drug resistance of single therapy, thus improving the therapeutic effect.
DRUG	Sintilimab	Sindilizumab (Sintilimab) is a humanized anti-PD-1 monoclonal antibody that has demonstrated promising anti-tumor activity in several cancer types. It works by blocking the binding of PD-1 to its ligands, PD-L1 and PD-L2, thereby lifting the inhibition of T-cells and restoring the immune system\'s killing function against tumor cells.
